Branson made most of his money of VG when sold off $1.4bn of shares just before their value tanked after that f**ked up first flight. I don't think he actually owned much of VG these days.

A few years ago but I converted about 50 Asus netbooks for local primary school to ChromeOS. The WiFi cards didn't work but I found compatible ones for a couple of quid each on fleabay. AFAIK they are still using a few of them today. Flex probably is a lot easier to install than the workarounds I had to use back then.
Re: Complexity ≠ Reliability
Yeah, its not clamp at launch time, relies on gravity. Engines start at 50% which is not enough lift off and then throttle up.
STS used explosive bolts and they had multiple instances of the bolds not cleanly separating correctly but fortunately not enough of an issue to stop the launch though once the SRB were lit there was no turning them off.
Re: Why all the cheering before the 10 second countdown?
The Van actually is actually owned by BocaChicaGirl (Mary) but is used by NSF. They have a video of them returning to the van. Its a right off and I'm pretty sure its not covered by insurance, lol. To be honest its a pretty old Dodge minivan and wasn't worth much.
I'll bite though I probably shouldn't.
SLS Block 1 has a 95T LEO capability. FH is around 63T.
Europa Clipper which was due to launch on SLS but has been switched to FH is probably a good use case for comparison. There were 3 factors which were cited,
- FH has enough performance to avoid gravity assist from Venus, something that Delta Heavy would need and the reason why DH couldn't be used.
- There is no capacity from Boeing for supplying the launch capability for a 2025 (at the latest) launch. All SLS capacity is allocated to Airtimes program. FH will take an additional year to get there which means it needs to launch in 2023 (it could launch in 2024 but call it 2023 to allow a performance buffer) but that is something that SpaceX can support.
- There is a potential vibration issue caused by the SRB. Boeing is stating one value but NASA's own wind tunnel testing is coming up with a different value. NASA has other SRB data from the shuttle era which supports their worries as well but didn't factor that into this report. Without actual launch data its impossible to discount the issue.
ARS Tech which is pretty reputable site has a good article on the switch. According to the article a fully expended FH launch is costing around $178m and there is a white house comment that SLS launch is $2bn excluding development in one of the linked articles. I was being pretty generous saying its 'only' a billion as that is what is in wiki.
Don't get me wrong here, I think SLS is the best option for Artemis. Its a direct flight, no messing about transferring crew, no in-flight refuelling, most proven technology and a bunch of other reasons. But as a general non-crew launch vehicle its a bit of a non-starter.
The SLS Wiki article SLS is over $1bn per launch, that is excluding all the development and maintenance costs. Falcon heavy fully expended is $150m for 2/3 of the LEO payload capacity. Of course there are missions that can't be done by FH due to fairing size limitations, lack of vertical integration and other capacity limitations.
Peering really isn't free or even cheap.
I have seen the data but I get the feeling they are only using a few ground stations which probably isn't helping. I haven't seen too many complaints about speed, seems to be jamming seems to be the main issue
Anyway, looks like he will continue to fund the donations for the time being.
Re: Believe it when I see it
They have been testing with Delta and I believe USAF. They have also been testing with F9 missions so I would think technically they are confident.
At the they don't have laser link work AFAIK so the plane has to be within 500 miles of a ground station which I thought might be an issue for trans Pacific flight ? Maybe sats in a higher orbit have a larger radius of coverage.
I believe the figure is around $10m but don't know if that is split between NASA and the other agencies. There is a breakdown somewhere, meal costs are $2k per day. Life support and toilet are around 20k per day (seems cheap). AFAIK, I don't believe Axiom have taken any supplies up with them.

Re: some in, some out
Why on earth are you paying £45 a month for 100mb ? I would be on the phone to retentions immediately. And as somebody else mentioned sounds like you are mixing bits and bytes. And starlink isn't designed for the masses and it's £90 a month for technology in the middle of being tested.

Re: On the negative throught
I doubt it, his reasoning for leaving is causing too many questions. If it was being caught with his pants down then the usual reason for leaving is to spend time with the family.
My guess is whistle blowing.
Expect him to pop up with one of the private agencies in the next couple of weeks.

Re: Anxious to find out how Teams will work?
We already have Office365 for most of the employees along with OneDrive and private SharePoint. Teams is a flick of a switch to enable. Integration is fine with rest of MS productions, for most people its just another collaboration tool. Like most enterprises the issue is that different teams go ahead and implement their own tools based on prior or personal experience and that just leads to fragmentation. God knows how much of the company is using WhatsApp for communicating.
